In textile industries, residual dyes and heavy metals are usually released into environment via wastewater effluent. Because of their negative effects not only to environment but also to human health, these contaminants are required to be removed from water environment. To achieve the effective adsorption of dye and heavy metal, the adsorption mechanism needs to be understood clearly. In this study, the complexity of adsorption of Remazol brilliant blue R (RBBR), methyl orange (MO), copper (Cu) ions, and iron (Fe) ions onto numerous natural adsorbents was analyzed using the modified mass transfer factor model (MMTF). The secondary adsorption data were collected from various sources. The study found that MMTF has a superior adaptability for describing the mechanism of the adsorption of dyes and heavy metals both in solely and in multi solute.
Silver nanoparticles (AgNPs) presence has considerable impact on microbial growth. In this paper, AgNPs was deposited on surface of four textiles to enhance the anti-microbial properties using immersion technique. Immersion technique was selected since it was simple, no need high energies, and no additional equipment required. In addition, AgNPs was synthesized using in situ-bio technique which is non-toxic, harmless and eco-friendly approach. Four textiles were evaluated, such as TA, TB, TC and TD. The finding projected that antifungal ability was correlated to the type of the textiles. TC textile has the significant antimicrobial activity with 12.33 ± 2.08 of inhibition zone which followed by TD (16.00 ± 3.46), TB (17.67 ± 7.09), and TA (17.67 ± 6.65). In addition, the surface bonding AgNPs on textile was possibility caused by the -OH group. It has a lone pair of electrons on the O atom that can interact with AgNPs to form –OAg bonds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
